Patent GB-1032574-A (GB)
Title: Electrical resistors
IPC: H01C17/232
Filed: 1963-05-31
Abstract: An electrical resistor is made by depositing a coating of an electrically conductive material on a non-conductive porous base member so that the conductive material fills at least part of the pores of the base member, and then heat-treating the unit to stabilize its temperature coefficient of resistance.  The porous base may be of sintered glass, porcelain, ceramic, or plastic. The coating is preferably applied by an autocatalytic reduction process in which a coating of a catalytic metal Fe, Co, Ni, Pt, Pd, Ru, Rh, Os, lr is first formed on the base which is then immersed in a solution containing nickel chloride, sodium hypophosphite as a reducing agent, and sodium acetate as a buffer and complexing agent for form a coating consisting of a mixture or compound of nickel and phosphorus; a coating containing cobalt may be formed similarly. If the pores are small, the treating solution may be subjected to ultra-sonic vibrations and may be applied under pressure; or the base may be evacuated before applying the solution.  For more even distribution of the coating, an electric current may be passed through electrodes attached to each end of the base.  Other methods of applying the coating are (a) deposition of aluminium from the vaporized metal in a carrier gas; (b) immersion in a slurry of nickel oxide, followed by drying and heating in a reducing atmosphere; (c) filling the pores with a gaseous or liquid hydrocarbon and reduction to carbon by heating. Terminals may be attached to the resistor by chemical deposition, electroplating, or direct bonding, or by fitting metal end caps. The resistor may be encapsulated in silicone, silicate, or epoxy resin.

Abstract: 618,890. Fluid-actuated valves. PEEBLES & CO., Ltd., and WATSON, A. M. July 23, 1946, No. 21978. [Class 135] In an automatic change-over valve device for connection to alternative sources of compressed gas, diaphragm-operated valves 1, 1A are spring-loaded differentially in valve-opening direction and have a common outlet 6 and means for effecting exchange loading of the valves. As shown, the valve 1 is heavily loaded by the spring 2 through the cam 2B connected to the lever 5 and is thus opened to allow gas to pass to the outlet and also to act on the diaphragm 3A, which is lightly loaded by the spring 2A through the cam 2C, to close the valve 1A. When the supply through the valve 1 is exhausted, the pressure on the diaphragm 3A falls and the valve 1A is opened. The lever 5 is turned through 180 degrees so that diaphragm 3A is heavily loaded and diaphragm 3 lightly loaded, and the pressure of the gas passing through the valve 1A acts on the diaphragm 3 and closes the valve 1.

Title: Reversible adjustable velocity ratio coupling
IPC: F16H3/44
Filed: 1952-09-03
Abstract: 727,066. Variable-speed gearing. ROCKWELL MANUFACTURING CO. Sept. 3, 1952 [Dec. 10, 1951], No. 22157/52. Class 80 (2). A variable ratio drive comprises an epicyclic train for continuously driving a driven shaft 16 from a driving shaft 14 which is acted upon cyclically by a variable amount to effect a supplementary movement of the driven shaft. The driving shaft 14 carries a cage 30, 32 in which are rotatably mounted double planet pinions 49, 53 and 51, 55 and a worm 46. The planet 49 is a worm gear and meshes with the worm 46, the pinions 51 and 53 are in engagement and the pinion 55 meshes with a sun gear 19 on the driven shaft 16. Such an arrangement provides a solid 1 to 1 drive but the invention provides means for cyclically acting on the worm 46 to impart an additional variable movement to the driven shaft 16 which comprise uni-directional driving devices 82, 96 acting on either end of the worm according to the direction of rotation of the gearing. The devices 82, 96 consist of sleeves which are oscillated by means of a fork member 108 having a follower 112 engaged in a groove of a stationary ring member 116 which member is adjustable about pivots 118, 120 by means of an arm 134 to vary the amplitude of the oscillation. The devices 82 or 96 transmit through wedging balls 70 the oscillating movement in one direction only to the worm 46 on each revolution of the driving shaft and thus an additional movement to the driven shaft. A wedging ball detent is associated with each uni-directional device 82, 96 to prevent reverse movement of members 56, 58 driven thereby. The engagement between members 56 or 58 and the worm 46 is effected through ratchet teeth according to the direction of rotation by means of a frictional drag imposed upon the sun gear 19 by a leaf spring 26.

Title: Pushbutton tuning assembly
IPC: H03J5/12
Filed: 1973-05-09
Abstract: 1427020 Cams &c GENERAL INSTRUMENT CORP 9 May 1973 [30 June 1972] 22174/73 Heading F2K [Also in Division H3] In a push-button tuning assembly comprising a slide A mounted on a frame D and a tuning control adjustment element B pivotally mounted on the slide for engaging a tuning control element C as the slide is moved leftwards a locking means F is mounted on the slide A and is effective on engagement of the adjustment element B with the tuning control element to lock the adjustment element B to the slide. Also a push-button mounting support G is secured to the slide A by means 44 allowing limited rectilinear sliding movement relative to the slide, an auxiliary member E is mounted on the slide A for limited movement leftwards relative to the slide in response to engagement of the adjusting element B with the tuning control element C and the locking means F is operatively connected to the slide A and the auxiliary member E so as to be actuated in response to the relative movement between the slide A and the auxiliary member E. On pressing in the push-button support G leftwards, an inclined cam surface such as slots 100 on one of the auxiliary members E or the push-button support G engages a cam follower such as projections 102 on the other of the auxiliary member E or the push-button support G so that the push-button support G and the slide A move in opposite directions perpendicular to the direction of sliding of the slide A. The auxiliary member E has a portion 36 spaced from the slide A and the push-button support G is received within the space between the slide A and the spaced portion 36. The inclined slots 100 and the projections 102 co-operate to ensure that the bottom edge of the slide A is maintained in contact with the bottom of a slot 104 in the front panel 84 and ensure that the top edge of the push-button support G is in engagement with the top of the slot 104. This provides accurate resetting of the position of a tuning cam B. To reset the tuning cam B to a new tuning position the push-button 78 is pulled out from the position shown in Fig. 8 to that shown in Fig. 3. On pulling out the button 78 the auxiliary member E slides relative to the slide A and a tab 34 is moved over the end of a lock lever 56 into a recess 72 shown in Fig. 3 to release a spring 54 from engaging the tuning cam B. With the treadel bars 90 adjusted to the new tuning position the pushbutton 78 is pushed in. The tuning cam B is then pivoted to the new tuning position set by engaging the treadle bars 90. On further pressing the button 78 the auxiliary member E slides relative to the slide A and the tab 34 passes over the end 73 of the lock lever 56 to the position shown in Fig. 8 where the tuning cam B is locked in position by engagement with the spring 54 at 66a. The push-button tuning assembly may be used for preset tuning of automobile radios.
